django - Docker Wordpress/Apache behind Docker Nginx - Port Number Issue

Question

I am having problems getting the wordpress docker image working with the nginx docker image.

The python/django container works perfectly fine with nginx, but the wordpress/apache one is having problems. I can get to the django site, with https. I cannot get into the wordpress one with https. In fact, when I go to my site site.com/wp, I get back site.com:8080/wp, so for some reason it is coming back through port 8080, and not 443 or 80. I've tried setting the wordpress site as the root location / (in the default.conf file) and it still has the same problem (then I get site.com:8080). The wordpress functionality is normal, I can edit the site as usual.

default.conf file for nginx

disable_symlinks off;
ssl_certificate xxx
ssl_certificate_key xxx

server {
    listen 80;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name site.com;

    location / {
        proxy_pass http://django:8000; #django container
    }

    location /static {
        alias /path/to/static;
    }

    location /wp {
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;        
        proxy_pass http://wordpress:80; #the wordpress container
    }
}

Answer 1

It seems like the wordpress container is pulling that 8080 port number from mysql, where I had it originally set for local testing.

Overriding the mysql stored site name worked for me, by adding these lines to wp-config.php

define( 'WP_HOME', 'https://' . $_SERVER['HTTP_HOST'] . '/' );
define( 'WP_SITEURL', 'https://' . $_SERVER['SERVER_NAME'] . '/' );
